Probabilistic analysis of a PR steel-concrete composite frame
The paper investigates the seismic performance of a partially-restrained steel-concrete frame using the probabilistic approach. The analyzed frame has been tested at the ELSA laboraotry of the Joint Research Centre of Ispra (Italy). The component method has been used to model both interior and exterior composite joints. The Latin Hypercube method has then been employed to draw the probabilistic distribution curves of the joints. Hence, the fagility and performance curves of the whole PR composite frame have beed determined for four limit states.
